CST, 7004P6, TMB Substrate

Detection System for studying in the research area. Product Usage Information (a) After incubation with horseradish peroxidase (HRP) conjugated secondary antibody, wash plates with PBS/0.05% Tween-20. (b) Add 100 μl of TMB solution/well. Incubate for specific amount of time or until desired signal is achieved. See product datasheet for recommended incubation times for specific antibody pair. (c) Add 100 μl of STOP solution. (d) Read Absorbance at 450 nm. Storage Store at 4 o C. Background TMB (3,3', 5,5"-tetramethylbenzidine) is used as a substrate to generate detectable signal in ELISA. The reaction between the TMB substrate and a peroxidase, typically horseradish peroxidase (HRP), produces a measureable color change that correlates with analyte level.
